The best figures in the history of the Champions Trophy are Farveez Maharoof's 9-2-14-6 for Sri Lanka against West Indies in 2006.
Maharoof is on fire (I wish I could take credit for that, I can't)

End of twitter postPlay is delayedpublished at 16:36 British Summer Time 2 June 2017
Either the players are having a five course banquet in the interval or play has been delayed.
It's definitely the latter, I'm afraid.
No sign yet as to when the rain will stop or how long the delay will be.

Neil Burns: From an English perspective a draw would be great!
Daniel Potter: Australia should win from here, only Southee and Boult to worry about, the other bowlers should not pose a problem at all
Dom Ford: Money on Hazlewood for leading wicket taker of the Champions Trophy 2017, has started well! He's lethal in English conditions.
Edgbaston as neutral venue for India v Pakistan?published at 16:27 British Summer Time 2 June 2017
As we wait to see if it clears or not, here's something to whet your appetite for the blockbuster game in Birmingham on Sunday.
Warwickshire chief executive Neil Snowball says they are "very interested" in becoming a neutral venue for Pakistan and India matches.
Oh dear ...published at 16:22 British Summer Time 2 June 2017
Sorry to bring you some bad news - It's raining at Edgbaston.
Not too sure how heavy it is at the moment.
But the below forecast doesn't fill me with much confidence.
Hazlewood mops up the tailpublished at 16:19 British Summer Time 2 June 2017
Unfortunately for Williamson and New Zealand, the Australian bowlers stepped up to the plate.
Josh Hazlewood in particular fancied getting back to the changing rooms early, sweeping up the last three wickets up in four balls.
Disappointing end to their innings but it's still a defendable score.
We're not too sure what the actual total Australia will chase is, as Mr Duckworth and Mr Lewis will have their say.
100 for Williamsonpublished at 16:15 British Summer Time 2 June 2017
Williamson upped the pace as he went on to score his ninth ODI century.
He was finally run out with 6.5 overs to go but had set up his middle-lower order to score a big total.
Over to you, skipperpublished at 16:12 British Summer Time 2 June 2017
Australia finally got the breakthrough and Ronchi was dismissed.
Captain Kane Williamson then took the reins. Albeit taking it slowly at first, he did a fantastic job in keeping the scoreboard ticking over in between some big scoring shots.

More of the same after the rain ...published at 16:08 British Summer Time 2 June 2017
I told you that the Ronchi innings was a good one.
As the players returned after the delay, and the match reduced to 46 overs, he carried on exactly where he left off to race to his half century.
Lifeline for Ronchi before the delaypublished at 16:05 British Summer Time 2 June 2017
This was a funny one. Australia, who have actually been pretty decent in the field today, made a meal out of this run-out chance.
After this, we lost a good chunk of the morning/early afternoon to rain.
Rocket Ronchipublished at 16:03 British Summer Time 2 June 2017
After Guptill departed, Ronchi really pressed on and treated us to some wonderful cricket.
He hit the ball to all parts of the Edgbaston ground.
An absolute joy to watch.
New Zealand started wellpublished at 15:59 British Summer Time 2 June 2017
Right, time for a recap.
The New Zealand openers Luke Ronchi and Martin Guptill got off to a solid start, putting on 40 in the first 5 or so overs.
The Australian bowlers really struggled to find their line and length at the start of the day.
Postpublished at 15:52 British Summer Time 2 June 2017
So, that collapse? New Zealand lost seven wickets for 37 runs in 5.5 overs. They were oh-so-well placed for a big finish but they faded away and Australia's seamers, led by Hazlewood, put in a good shift at the end.
WICKET - NZ 291 all outpublished at 45 overs
Boult 0 c Wade b Hazlewood
Last man Trent Boult negotiates the hat-trick ball, and then edges the next one behind!
New Zealand were 254-3 and they're all out for 291. That was some collapse at the end. Credit to Australia for coming back from a difficult morning, particularly Josh Hazlewood, who walks off with tidy figures of 6-52 from his nine overs.
WICKETpublished at 44.4 overs
Santner c Smith b Hazlewood 8 (NZ 291-9)
Five for Hazlewood! Santner was trying to clear the ropes again and that's a very, very good catch from skipper Steve Smith. Smith was leaping up into the air and managed to snaffle it up with two hands.

Here's Tim Southee. Who, er, has one style of batting.
WICKETpublished at 44.3 overs
Milne c Maxwell b Hazlewood 11 (NZ 291-8)
Glenn Maxwell makes taking catches look so easy. That's actually a really good pull shot from Milne, the ball making a proper crack off the bat, but he just couldn't clear Maxwell on the boundary. Just prior to that, Milne had smashed a lovely pull shot for four.
